- To reduce confuse rename the parts of linuxbios bios that run from
ram linuxbios_ram instead of linuxbios_c and linuxbios_payload... - Reordered the linker sections so the LinuxBIOS fallback image can take more the 64KiB on x86 - ROM_IMAGE_SIZE now will work when it is specified as larger than 64KiB. - Tweaked the reset16.inc and reset16.lds to move the sanity check to see if everything will work. - Start using romcc's built in preprocessor (This will simplify header compiler checks) - Add helper functions for examining all of the resources - Remove debug strings from chip.h - Add llshell to src/arch/i386/llshell (Sometime later I can try it...) - Add the ability to catch exceptions on x86 - Add gdb_stub support to x86 - Removed old cpu options - Added an option so we can detect movnti support - Remove some duplicate definitions from pci_ids.h - Remove the 64bit resource code in amdk8/northbridge.c in preparation for making it generic - Minor romcc bug fixes git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1727 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

2) In raminit.inc (or whatever), make a jmp out to low_level_shell, setting

// intel_chip_post_macro(0xf1)
|

// jmp .Lhlt

otherwise, a ramtest failure will hang

4) build and flash as normal

If it worked, the speaker will beep, and you'll get a shell.
